LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 662,582, dated November 27, 1900.

Application filed September 24, 1900- Serial No. 30,895. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, FRANK THEODORE WIL- LIAMs, a citizen of the United States, residing at Meriden, New Haven county, Connecticut, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a full,clear, and exact description.

My invention relates to oil-lamps 'of the central-draft type, and particularly to the construction of the burner.

The chief object of my invention is to provide a simple, inexpensive, and effective means whereby the wick cannot be raised to an unnecessary or dangerous height. To raise a lamp-wick beyond the proper height results in imperfect combustion, and as a consequence the flame is a smoky one. To limit the height, however, that the wick can be raised is to prevent this undesirable result, and as a consequence a lamp provided with a burner constructed as hereinafter described may be used with the greatest safety and economy.

In the drawing the figure illustrates a lampburner embodying my invention.

A is an outer wick-tube. B is an inner wick-tube. C is awick movable between said tubes. The Wick may be raised or lowered by any of the well-known wick-lift devices. (No shown.)

D is a wick guard and stop of annular form supported above and independent of the wick and stationary with respect thereto. This guard D may have a depending wall E, which may be attached thereto by connections E, the spaces between said connections forming gas-openings adjacent the inner side of the wick when same is raised.

G is a stationary spreader supported upon a ledge H' upon a rod H and securely held in a fixed position by means of a cap or set nut I.

G is an annular depression or groove extending around the spreader adjacent the guard D.

The spreader G may be perforated in the usual manner. By preference the supporting-shoulder I-I is adjustable, as by a screwthreaded connection, so that the spreader and the guard D may be moved to exactly the right height and there firmly and positively secured. The guard D receives its support from the spreader. In the construction shown this connection is made through the medium of the Wall E; but for the purpose of facilitating cleaning the guard and wall E may be removable, so as to give sufficient room to thoroughly clean the parts that would otherwise be reached with difficulty. The annular depression G' in the spreader forms a space sufficiently large to permit the products of combustion to flow freely from the inner side of the wick upwardly, where they will mingle with the products of combustion flowing from the outer side of the wick. In this way there will be two roots to the flame, one at the outer and another at the inner side of the wick, which when they unite above the guard D give a brilliant and steady light. One advantage of this construction is that the wick is relieved of the burden of supporting either the spreader or the wick-guard. This is due to the fact that the wick-guard is stationary and supported at the proper height of the wick to stop it at a point where the best results may be attained.

By the foregoing means the stationary wickguard may be located upon exactly the right plane to prevent the raising of the wick excepting at a uniform height entirely around the wick-tubes. Consequently the iiame will be of a uniform size.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a device of the character described in combination, al1 inner and an outer wick-tube forming between them a passage for a wick, a stationary spreader cylindrical in form, a stationary annular wick guard and stop located above the wick and above the wicktubes, and an annular gas-passage between the inner edge of said wick-guard and said spreader.

2. In a device of the character described in combination, an inner and an outer wick-'tube forming between them a passage for a wick, a stationary spreader cylindrical in form, a stationary 4annular wick guard and stop l0- cated above the wick and above the wicktubes, an annular depression in said spreader IOO adjacent said wick-guard and the inner side of said wick and means for adj usting` the p0- sition of the spreader.

3. In a device of the character described in combination, an inner and an outer wick-tube forming between them a passage for a wick, a stationary spreader cylindrical inV form, a stationary annular wick guard yand stop connected to said spreader located above the wick and above the wick-tubes, an annular depression in said spreader adjacent said wickguard and the inner side of said Wick, and means for adjusting the position of the spreader.

4. In a device of the character described in combination, an inner and an outer wick-tube forming between them a passage for a wick, a stationary spreader cylindrical in form, a stationary annular Wick guard and stop located above the wick-tubes and in line with the Wick, a space between the inner edge of said Wick-guard and the spreader forming a gas-passage adjacent the inner side of the Wick.

Signed at Meriden, Connecticut, this 15th day of September, 1900.
